-If you have to dose so much vinegar a day , isn`t it better then to dose pure acetic acid ?
It would save you the hassle to buy so much bottles of vinegar every week ...
Well, one gallon of vinegar costs $2.59 and lasts about 10 days at the super high dose, and maybe 3 weeks at the current dose, so expense and bother is not a big deal. My dosing pump sucks it directly from the gallon jug.
